LOCK MECHANISM FOR CONCEALED-HAMMER GUNS.

SPECIFICATION forming part of Letters Patent No. 315,413, dated April 7,1885.

Application filed October 18, 1884.

To all whom it may concern:

Be it known that I, ANDREW HYDE, a citizen of the United States,residing at Hatfield, in the county of Hampshire and State of Massachusetts, haveinvented a new and useful Improvement in Hammerless,otherwise called Concealed-Hammer, Guns, of which the following is aspecification.

The first part of my invention consists of the construction and relativearrangement in a hammerless-gun of a locking-bolt, one or more internalhammers or strikers, and an actuating hand-lever, whereby in onemovement of the hand-lever the striker or strikers are brought to ahalf-cock and the bolt moved to release the barrels.

The second part consists in the construction and relative arrangement ina hammerless gun, ofone or more pivoted hammers or strikers, and abolt-releasing hand-lever, whereby, by means of the hand-lever, thestriker or strikers may be brought from a fired position to a half-cockand from a half-cock to a full-cock.

The third part consists in the construction and relative arrangement ina hammerless gun, of one or more strikers and a bolt-releasinghand-lever, whereby the hand-lever is adapted to ease the strikers froma full-cock to a halfcock position, or beyond it. I

My invention is fully illustrated in the accompanying drawings, inwhich- Figure I is an elevation in section through the receiver of ahammerless gun, showing one striker down and showing the relativeposition of the other parts thereto. Fig. II is the same view of thereceiver, showing the striker brought to a halfcock, and thelocking-bolt in the act of being moved to release the barrels. Fig. IIIshows the striker brought to a full-cock or in the act of being loweredfrom that position, and Figs. IV and V are detail views.

I A is the receiver.

(No model.)

surface upon the lever C opposed to the spring end (1.

E is a hammer or striker contained within the receiver, pivoted upon apin at 6, provided with a1nainspring,and adapted to be engaged by thetrigger-dog. The striker E is also provided with a rear extension ortail, G.

H is an action-lever pivoted at one end, and adapted to have its otherswing through a slot in the top of the receiver.

I is a bearing-surface upon the pivoted end of lever H, and conformingto the bearingsurface D of lever G.

K is ashoulder upon the pivoted end of lever H, and adapted to comeagainst and hook over the upper front corner of the striker E.

J is an under surface of lever H, and adapted to bear against the upperextreme end of tail G of striker E; and m is aspring in the receiveradapted to bear against the free end of lever H to hold it normally inthe position shown in Fig. I.

The lever H is arranged relatively to the bolt-lever O and striker E tohave its pivoted head interposed between the two, and to have itssurface I and shoulder K upon opposite sides of its pivot h operate todistend the lever O and striker E upon an upward swing of lever H.

The lever H is arranged, when in an inoperative position, as shown inFig. I, with the striker down, and as it would be in Fig. III were itreleased by the hand, to have its surface I coincide with thespring'distended surface D of lever O, and to have its free end held byspringm immediately above and in contact or close to the tail G of thestriker. The surface D of lever O bears only to one side of pivot h uponlever H, to adapt the lever O to be moved only by the upward swing oflever H, while remaining unaffected by the downward swing of lever H.

The operation of the mechanism is as follows: The barrels being looked,as indicated by the bolt 13 in Fig. I, and the striker being down, asshown in the same figure, when it is desired to break the barrels away,the lever is pushed up by hand, as shown in Fig. II, in that motionbringing the striker to a half-cock and withdrawing the bolt to releasethe barrels, and bringing the striker to a half-cock at a short intervalbefore the barrels are released. The barrels being released, a removalof the pressure from leverHpermits the spring (1, acting throughsurfaces D I, to restore the lever H to the position shown in Fig. I.The striker being ata half-cock, it will be seen that the loaded barrelscan be locked to the breech without disturbing the striker in itshalf-cock position. When it isdesired to full-cock the striker, adownward pressure of the hand upon lever H, as shown in Fig. III, bearssaid lever upon the tail G ofthe striker,- tobringitto a full-cock, thespring 'm, as aforesaid, returning lever H, when manually released, tothe position seen in Fig. I; and it will be seen that the play of leverH under the hand opposed only by the slight spring m, acts as a sureindicator of the full-cock position of the striker. The parts being inthe position shown in Fig. I, a downward pressure of the hand upon leverH, as shown in Fig. III, will bring the striker to a half-cock, as wellas it would be brought to the same position by an upward movement ofsaid lever, as before de scribed, and this is important for the reasonthat sometimes from fouling or rusting the bolt B will stick, and inorder to exert the full fc rce of the hand to start said bolt, it isdesirable to get the power of the mainspring exerted through the strikerout of the way, which is accomplished by bringing the striker to ahalf-cock by a downward pressure upon lever H.

Should the bolt B from any cause remain stuck in the position seen inFig. II, the lever H,being in the position seen in Fig. I, would showagap between the surfaces D I, which gap would indicate to the eye thefailure of bolt B to lock the barrels.

In the drawings it is deemed sufficient to illustrate the invention byshowing only one striker with its trigger and mainspring, the two beingthe usual counterparts, and as a convenient way of operating bothstrikers by a centrally-disposed lever,H, working through a narrowopening in the top of the receiver, projections g, in reverse directionsfrom the tails G of strikers E, come under surface J of lever H to beacted upon by it, as the top surface of a single striker would be. Theend view of one-striker is shown in Fig. V; also, to more clearlyillustrate the action of the parts,the striker E is shown in rear of thelever O, and a firing-pin, L, represented as interposed between thestriker and acartridge; but without a departure from the spirit of myintion, the strikers having firing-points may be arranged upon each sideof lever O, and the lever H straddling the lever C may act on a surface,D, arranged upon the end 01, it only being important that the lever Hshould distend a spring-actuated bolt-lever and a striker to sosimultaneously move them, to be in turn restored by said spring.

In Fig. IV an end view of lever H is'shown, openings Z permittingthefiring-pins L to pass through the shoulder K.

I By these meansIam able to provide ahammerless gun combining theadvantages of a hammer-gun...

Having described my invention, what I claim is- 1. In abreech-loadinggun of the character described, the barrel-locking bolt, a pivoted leverbearing thereon, a spring bearing on said lever, a pivoted hammer havingusual trigger mechanism, and an action-lever pivoted, substantially asdescribed, to bear on one side of the pivot on the bolt-operating leverand on the other side to bear on the hammer when said lever is actuated,the combination being and operating substantially as described.

2. In a concealed-hammer gun, the combination of a barrel-locking bolt,a pivoted operating-lever engaging therewith, a spring bearing on oneside of said lever, a pivoted hammer having the usual trigger mechanism,an action-lever pivoted in the upper portion of the frame, having anextension above its' pivot engaging the bolt-operating lever and anextension below its pivot engaging the front of the hammer when suitablyactuated,

substantially as described.

3. In a concealed-hammer gun, the pivoted hammer having a rearwardextension, (and. usual trigger mechanism,) and the actionlever, pivoted,as described, so as to enter the top of the frame in rear of its pivotand bear directly on the extension of the hammer, combined substantiallyas described. I

4. A slotted gun-frame, a pivoted hammer within said frame in line withthe slot, and an action-lever pivoted in the frame, having a projectionwhich enters the slot in front of the hammer-pivot and a projection inrear of the hammer-pivot, said projections engaging the hammeralternately when suitablyactuated, the combination being and operatingsubstantially as described.

5. In a concealed-hammer gun, the combination of a' slidinglocking-bolt, an operating lever engaging therewith, a spring bearing onone side of said lever, a pivoted hammer in usual location and havingrear extension, an

action-lever pivoted in the frame and having engagement above its pivotwith the bolt-lever and below its pivot with the face of the hammer,(when said lever is actuated in one direction,) said action-leverengaging also the rearward extension of hammer when actuated in areverse direct-ion, all being and operating substantially as stated.
